Effects of model incompleteness on the drift-scan calibration of radio telescopes

Bharat K. Gehlot, Daniel C. Jacobs, Judd D. Bowman +76

Precision calibration poses challenges to experiments probing the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and Epoch of Reionization (z~30-6). In both inter…

Redundant-Baseline Calibration of the Hydrogen Epoch of Reionization Array

Joshua S. Dillon, Max Lee, Zaki S. Ali +76

In 21 cm cosmology, precision calibration is key to the separation of the neutral hydrogen signal from very bright but spectrally-smooth astrophysical foregrounds. The Hydrogen Epo…
